How to Calculate a Discount

Calculating a discount is straightforward:

Percentage Discount

Final Price = Original Price × (1 - Discount% / 100)

For example, a $100 item with a 25% discount: $100 × (1 - 25/100) = $100 × 0.75 = $75.00

Your savings: $100 - $75 = $25.00

Fixed Amount Discount

Final Price = Original Price - Discount Amount

For example, a $100 item with a $15 discount: $100 - $15 = $85.00

With Tax

When tax is included, it's applied to the discounted price:

Final Price = (Original Price - Discount) × (1 + Tax% / 100)

For example, a $100 item with 20% discount and 8% tax: ($100 - $20) × 1.08 = $80 × 1.08 = $86.40

Common Discount Scenarios

Buy One Get One (BOGO)

BOGO deals are effectively a 50% discount when you buy both items. For example, if one item costs $30, two items would normally cost $60. With BOGO, you pay $30 for two items, saving $30 (50% off the total).

Stacking Discounts

When multiple discounts apply, they're usually applied sequentially, not added together. For example, a 20% discount followed by an additional 10% off:

$100 → 20% off = $80 → 10% off of $80 = $72 (28% total savings, not 30%)

Clearance + Coupon

Many retailers apply coupons to the already-discounted price. A $100 item marked down 30% to $70, with an additional $10 coupon, becomes $60 (40% total savings).

Frequently Asked Questions

How do I calculate a percentage discount?

Multiply the original price by the discount percentage (as a decimal), then subtract from the original price. For a 30% discount on $50: $50 × 0.30 = $15 savings, so the final price is $50 - $15 = $35.

What's better: percentage or fixed amount discounts?

It depends on the original price. Percentage discounts scale with the item price (better for expensive items), while fixed amount discounts provide consistent savings regardless of price. For example, 20% off a $100 item saves $20, but $25 off saves more even though the percentage is lower.

How do you calculate discount percentage from two prices?

Use the formula: ((Original Price - Sale Price) / Original Price) × 100. For example, if an item was $80 and is now $60: (($80 - $60) / $80) × 100 = 25% discount.

Should tax be calculated before or after the discount?

Tax is always calculated on the final sale price (after discount). If you buy a $100 item with 20% off and 8% tax: discount first ($80), then add tax ($80 × 1.08 = $86.40).

What does "up to 70% off" really mean?

Retailers use "up to" to indicate the maximum discount available on select items. Most items will have smaller discounts. Always check the actual discount on the specific item you're buying.

How do I compare discounts from different stores?

Use the comparison mode above to enter each store's original price and discount. Don't forget to factor in additional costs like shipping, tax, and return policies when comparing.
